Which springs should I get?

[jschrauwen]

Right now, the only thing I have to correct toe/camber are adjustable tension rods and adjustable camber arms.

I pretty much have the same. Ebay rear upper adjustable control arm, AMS front adjustable upper control arms and Speedline (Ebay) adjustable tension rods but I've got new AMS front tension rods to install shortly since the current Speedline ones won't adjust far enough to correct my caster.This will all be corrected at the end of the month when I get my new AMS coilovers installed.

Quote »If the op wants to go with eibechs at only .8 drop there is no reason the car wouldn't be better than oem as long as he gets the other parts to bring everything back to spec. [/quote]The "bringing the car back to spec", you speak of is done primarily to help correct camber (and caster when necessary) due to any height change to help the tires wear better - and hopefully have a contact patch that stays somewhat even with the road's surface. But this doesn't have anything to do with the spring rates, shock damping rates, bushing compliance, sway bar sizes, or anything else needed to make everything work in harmony with the existing multi-links or (usually modified) tire sizes.

This would be necessary to get even, reliable results, as well as to maintain the neutral balance the car had initially. But who cares about that, right...as long as the car is low and stiff, lol. This is why those "in the know" buy completely matched packages...all pieces made together, and by a reputable source, where you know they have actually done true R&D.

Bottom line, that statement shows you don't know anything about suspension geometry and the complex science it is, even if I am the only one here that realizes it. For the Z to be a truly neutral car that doesn't feel as heavy as it is, Nissan spent millions using Cray supercomputing to design the multilink suspension which does its magic with very precise parameters...the EXACT reason they did not allow for any camber or caster adjustments...as even the slightest variation throws things out of wack. How you could think that using "just whatever" pieces you like won't throw geometry off blalance completely baffles me. In other words, just because *you* can't tell the difference doesn't mean there isn't one.

Quote »Yes on wheels a staggard setup wont do much but then what did that have to do with springs? yes many will cut corners and there car will suffer cause of it, but that doesn't mean everyones car is going to be worse than it would have been had they stayed oem.[/quote]Once again, this shows you don't know shizza, so I am probably wasting my time replying, but...Adding a staggered setup to a car that is tuned for matched tire sizes will dial in understeer, usually to a terminal extent with the typical plus three or greater people choose for NA's these days. So the connection was that most people's mix and matched suspensions are even further from being right when they simply choose the "sick" looking staggered wheel package for their NA. My point was that at least with (good) OE parts, they would have a "true handling" balanced setup...even if it's not "track ready", or "cool with the kids low". So if one is going to throw all of this money at it, at least do it 100% right...get a fully engineered (matched) package and use the tire sizes the setup was tuned. If not, just go OEM...and have an excellent handling car with no guesswork...nor empty wallet.

Maybe you should re read what i said instead of being an idiot. i agreed with you on the staggard setup comment you made. And as for suspension i would suppose you feel that those companies that make coilovers and the like don't know what they are doing as well cause they "lower" the car which according to you even with their r&d will through the specs off even with the corrolating parts. Also hard to take anyone seriously when they use words like "shizza"

Let me get back to you when I get to that point. I don't want to get ahead of myself.

Heh, I'm secretly waiting for that moment! I remember when you posted up that thread on the coilovers, I just about fell over hahaha. Yeah, my tension rods don't adjust enough either *or at least, I think so*.. I'm trying to save up to get all new AMS stuff, so hopefully that'll work out!

I wish powertrix would make a bundle pack for the front and rear upper control arms and their tension rods like the ams package.

1. Maybe you should re read what i said instead of being an idiot.

2. And as for suspension i would suppose you feel that those companies that make coilovers and the like don't know what they are doing as well cause they "lower" the car which according to you

3. even with their r&d...

1. I would think the idiot would be the person that thinks one can simply "put things back right" with a couple of alignment adjustment pieces and custom alignment...after picking whatever "upgrade salad" one wants without any giving any thought to suspension geometry conflicts, changes and complexity. Even funnier is your claim that "there's no reason it shouldn't be better than" a stock vehicle (your words again). Ask, a (real) engineer...there are hundreds of reasons that is less than likely. Of course if you ask the people selling the product, they would have a totally different story, but it doesn't take Einstein to realize this. And let's face it, you automatically know more than me because I said "shizza" anyway.

2. They know what they are doing. It's called making money, lol. Do you have any idea what it would actually cost in R&D to make a suspension that keeps the original balance of a vehicle, yet improves grip, while lowering the car? Don't get me wrong, some of the big guys do aspire for such a setup, and arguably succeed. But as I mentioned...and these will come with everything needed to make that so.

But even you should be able to understand why using, say, one of their parts with pieces from somebody else, and whatever size tires one wants is going to throw off everything...even if "Billy Joe Alignment Shop" can correct camber, apparently the fix all to you?

3. Yeah, those Ebay and middlegrade "we have a shock for every import" companies spend billions in Z32 specific R&D and have banks of engineers on staff that can truly make the suspension Nissan was not able to. Run with that. The bottom line is that they got your money...and you are convinced your parts are gold...so who's to question that strategy? Maybe I should market something...

Hint I am on stock suspension still so no one has my money. And where it would go is likely to powertrix or spl who both have done extensive testing on the track and off on their products to improve the suspension specifically for the and get this now "z32".

Prove that. I don't mean brochures, websell, or "marketing speak" either.

Hint I am on stock suspension

I get the distinct impression that carcrazyguy advocates stock and only stock suspension replacement parts.I guess that's a choice one can make or not. Imagine how boring sportscar ownership would be if the only part replacement was oem only. No personalization, no making your own personal statement, no individual efforts to try and improve current configurations.Well I do agree that we should not try to assume we know better than the factory engineers, there have been improvements made to numerous automotive systems that have gradually made their way to specific systems on the Z32. Granted there are going to be questionable products and I believe I've purchased my share of them and hopefully have learned my lesson in those areas.To me it comes down to the individual who decides what he wants to mod and later determines if he had made a wise choice/decision based on the anticipated results. To me, that's what matters. Being as informed and conversant in those areas of modification prior to purchase and install will usually lead to the desired outcome. Being the most informed consumer is the key. In the end it's personal choice. It's always been and will always be that way. Advocating oem and nothing but oem will more than likely fall on deaf ears. I'd like to think that with more than 20 years since the first Z32 rolled out, that there have been enough progress and improvements in design and manufacture of suspension parts, even for the Z32.

1.. LOL, Actually, I never said that, meant that, etc. But Z-owned slickly gave me that characteristic a couple replies back...which apparently worked to make others assume that too. I know you are a pretty sharp guy...so even if Z-owned doesn't know anything about the technical aspects of things, I see he is pretty good at argument winning techniques...for example him saying I could not be taken seriously due to a slang (Deutsch) word being used.

But to clear things up, I will go on record as saying I do prefer (new) OEM over mix and match suspension upgrading. My original point (that got slurred by superslick Z-owned) is that at least if a person replaces all worn parts with OE items, they will have a perfectly balanced, well handling car. By comparison, buying shock A and spring B and so on will produce quite unpredictable, and often unexpected results. But give me, say, the (equivalent of) the SMZ suspension on a TT, that would be a different story, lol.

2. Yes, I agree, as there is one stiff rule on forums. What one did is always best - and will be defended to the end. So anyone that either has done the modification in question, or dreams of it, they will be absolutely deaf to even the most logical argument.

3. You would think...but not really. Read engineering trades, articles, etc. in the past decade in these areas. Heck, even the 350 and 370Z suspensions are tightly based on the Z32 multi-link design with no major engineering changes...well, other than those necessary to suit the differing vehicle.

Also, notice that new vehicles (other than exotics) aren't turning the g's that RX7's, Z's, Supra, etc. did in the mid 90's. Sure, some of this is financial, but in these areas, progress has hit the proverbial wall...just as physics itself has (other than maybe select Quantum theories).

But even if there was a major development made, this is not going to translate into aftermarket shocks and springs, and especially not a discovery an Ebay or multi-shock company has found and is keeping from the world.

A progressive development would however, be seen in a whole new design (similar to what multi-link, wishbone, etc was in the 80's). But "performance" replacement shocks, springs, etc. are basically the same part that have been around for decades, with only differing rates, etc. and along the same lines, math has not varied much either. But I do hear that statement said often on forums...usually when people justify an expensive ECU upgrade on an NA for example. And I do know how "sold" on that concept people are...as it will cleanly and often completely justify any upgrade...or motivate those that might be on the fence. So if ears remain deaf...so be it.

^^^ All excellent points.I guess to elaborate a bit on what I was hinting at would be for an example the front adjustable upper control arms.Not being in the Z scene very long, to me it seemed that Stillen had come out with something that proved to work well for his lowering projects. I did use his first gen adjuster for about a year and found it worked well for my needs. I later changed it out in favour of a midori style adjuster. The midori adjusted ahs been produced by a number of different vendors, each perhaps putting their own touches where they felt necessary including Stillen himself with his second gen adjuster.Some have shown areas for improvement and they were duely corrected. While I'm not an engineer and don't profess to know the intricacies (sp) of suspension dynamics, replacing small specific items with non oe parts to compliment improvements in corresponding areas (shocks/springs/coilovers) is and should be a necessary thing in order to maintain an even balance of parts that should/will work in harmony with each other. Sometimes people don't quite get the right combination correct the first time (like me) by not making themselves completely conversant with their modification upgrades. OR, they lack the funds to do it right the first time. Whichever the case, they may eventually pay a higher price for the err.By always going oem one can almost always achieve guaranteed/predictable results all of the time as designed by the factory engineers. But these are usually not what the average Z owner today wants. And because of that, there will be options and avenues that differ from oem because there's a demand for it.

Eibachs orderd and 300 degree camber ordered

Congrats, I think you'll like them. You did mention in a previous post that you already have shocks to go with these new springs but I don't recall what they wre. Are they new?FWIW, those that do a new install of this sort they're usually replacing old/worn oem parts. As such it's normally recommended to get the "Nissan OEM 300ZX Full Shock Rubber Bushings/Gasket Kit(KYB Also)" from CZP. http://www.conceptzperformance...4.103This is usually an accepted part of the process to assist with the longevity of those new shocks and springs you're installing.I got that kit from Coz a few years ago and it's very comprehensive and worthwhile.Just thought I'd throw that out there.Cheers and good luck with the new goodies.

My car is currently sitting on megan 2inch drop springs with tokico blues. I have no camber correction kit or anything and it rides flawlessly.
